核岛通风系统防火设计
Fire protection design for ventilation system of nuclear power plants
摘要：
对核电厂的防火分区进行了详细介绍，并与民用建筑的防火分区进行了对比。对核电厂各厂房通风系统的防火设计进行了详细分析，介绍了被动防火和主动防火2种措施的应用，并对防排烟和加压送风系统的设计进行了详细说明。最后通过分析防火设计满足辐射分区和单一故障准则的要求，说明了核电厂通风系统的防火设计满足核安全的要求。

Abstract：
Analyses the design of fire protection zone for nuclear power plants, and compares with that in the civil buildings. Presents the fire protection design of ventilation system for each workshop of nuclear power plants in detail and the application of active fire protection and passive fire protection measures. Analyses the design of the smoke control and extraction system and pressurization supply system in detail. It is proved that the fire protection design can meet the requirements of radioactive zone and single failure rule, so the design is safety for nuclear power plants.
